The plant for waste water treatment contains, arranged in the direction of flow of the waste water: an inlet (1) in which are arranged connection pieces (8, 9) for waste water withdrawal and for return of the unpurified water. The entry of a circulation pump (14) is connected to the connection piece (8) for waste water withdrawal by means of a pipe (12), which pipe is connected to a control block (35). A sensor (15) of the water dilution in the pipe is mounted on the pipe (12) which connects the connection piece (8) for waste water withdrawal to the entry of the circulation pump (14), which sensor is connected to the control block (35). The exit of the circulation pump (14) is connected directly to the connection piece (9) for return of the unpurified water. A flotation apparatus (21) is also provided, which is connected to the exit of the circulation pump (14) via a pressure line (18) of constant water throughput. An automatic shut-off valve (19) is arranged in the pressure line (18) of constant water throughput, which shut-off valve is connected to the control block (35). A vessel (25) for sludge collection and a vessel (23) for purified water are connected to the flotation apparatus (21), which vessels possess correspondingly a pump (30) for pumping out sludge and a pump (28) for pumping out purified water, which pumps are connected to the control block (35). Sensors (2, 3) mounted in the sewage tank (4) for the upper and lower water level are also connected to the control block (35). <IMAGE> |
